SPECIFICATION forming part of Letters Patent No. 501,143, dated July 11, 1893.

Application filed March 3l, 1893. Serial No. 468,548. (No model.)

To all whom it may concern,.-

Be it known that I, JOHN W. HILTON, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain newand useful Improvements in Stoves or Heaters; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the annexed drawings, which form part of this specification.

This invention relates to the peculiar form of stove or heater seen in a patent granted April 4, 1893, to myself and Benjamin P. Newell, and the first part of my present improvements comprises a novel combination of devices for counterbalancing the reciprocating grate, described in said patent, the details of said combination being hereinafter more fully explained.

The second part of my improvements comprises a novel combination of devices for operating a feed wheel that supplies coal to the stove-furnace, as hereinafter more fully described. e

In the annexed drawings, Figure 1 is a side elevation showing my improvements applied to a heating stove, the reciprocating grate being in its normal position. Fig. 2 is a vertical section taken from front to rear of the stove, the grate being elevated to permit it being re-charged. Fig. 3 is an enlarged vertical section through one of the grate-lugs and its accessories.

A represents the outer shell or casing of a stove, or range, or other similar heating apparatus, which casing may be of any desired shape in horizontal section, although it is preferably square. a represents the furnace door of .this casing, a the ash-pit door, and a the neck or collar to which the smoke pipe is fitted.

Bis a furnace-lining, properly secured within the casing, and C is a box or frame adapted to move freely up and down between said lining and casing. Furthermore, this foursided box is open at top, but provided at bottom with grate bars D, having, usually, the semi-circular shape seen in Fig. 2. Projecting outwardly from the opposite sides of this 5o box are lugs c, c', that traverse vertical slots E, of the casing, and these lugs carry slides Vl', and J.

F, F', that cover said slots at all times, and prevent any escape of fire or smoke from this part of the stove or heater. These slides are confined to a vertical path by guides f, f', secured to the casing. Attached to lug cis one end of a chain or wire rope G, which after passing over grooved pulleys H, I, has a weight J secured to its other end, and these devices are duplicated on the opposite side of the stove, as indicated by the dotted lines G', H', Either one of these ropes must be furnished with a pair of stops g, g', capable of operating a brake K, through one end of which the ropepasses freely. This brake is pivoted to the casing at k, and is so curved as to bear against the periphery of a drum L, the latter being secured to a horizontal shaft Z, that carries a revolving feed-wheel M. This wheel consists of a hub armed with a series of radial blades and is journaled near the upper end of an inclined chute N, adapted to discharge coal or other fuel directly into the fire-box Of the stove. Chute N constitutes part of a magazine O, mounted upon the stove, and having ahinged lid o at top, the bottom of this magazine being inclined down toward the wheel M, as seen at o.

P is an inclined cut-off, capable of being adjusted either up or down, by means of the bolt p, so as to regulate the feed of fuel from the magazine, which latter should be considerably higher than seen in the drawings.

R is a fixed supplementary grate, the bars of Which should be relatively nearer together than those of the main grate D.

The operation of this heating apparatus is, as follows:-The weights J, J', must be sufficient to cause an elevation of the grate O D, before the fire in the furnace has burned too low, which proper application of said weights is all the attention the stove will require. Therefore, when the stove is charged with fuel, the grate will be forced down to the position indicated by the dotted lines in Fig. 1, and during this descent, the coal flows freely from the magazine O, because there is now nothing to prevent the turning of feed-Wheel M. This wheel is automatically turned by the descent of coal within the chute N, the blades of said Wheel serving to scatter o r separate the fuel and prevent it being deposited IOO Consequently, a dead lock is now applied to the feed Wheel M, and no more coal can enter the stove While the grate is thus depressed. Therefore, there will be no danger of the lire being smothered by an excessive supply of fuel, neither Will it be necessary to examine the furnace constantly to see if there is enough coal in it. But as the coal is consumed, the weight in the grate gradually diminishes, and eventually becomes less than that of the counterbalances J, J', and then these counterbalances at once liftlsaid grate to the position seen in` Fig. 2, which act bringsthe lower stop g' of rope G, in contact with the lever of brake Kyand` removes pressure from the drum L. By thus removing pressure from said drum, the feed Wheel M is again free to turn and deliver coal into the stove, as `above described. If the descent of the main grate should cause any large lumps of coal to rattle through between the bars D, these lumps will be arrested by the supplementary grate R and then consumed. Finally, the chains, pulleys, Weights and other operative parts of the heating apparatus can be housed Within an outer jacket, to prevent them being tampered with I claim as my inventionl. The combination, in a heating apparatus, of a casing, a counterbalanced reciprocating-grate fitted therein, a magazine mounted upon said casing, a chute leading from the latter and discharging into the fire-box, a revolving feed Wheel journaled across said chute,

a drum secured to the shaft of said Wheel, andV a brake adapted to act against said drum,

which brake is operated by a connection that sides, a reciprocating grate C D fitted in said casing and provided with lugs c c', that traverse said slots, flexible Aconnections G, G', attached to said lugs and carried` over pulleys H, H', Weights J J', suspendedfrom said'connections,stops g, g', secured tooneof the latter, :a'chute N leading into the heater,a feed Wheel M, jourlnaled in. said chute, a drum L fastened to the shaft Z of said Wheelpandla brake Kiadapted to act against-said drum,in the `manner described, said brake beingoperated by saidstops g, g' for the purposestated. Intestimony whereof lafx` my signature in presence of two Witnesses.
